Bodyguard Alberto Alvarez was fired by Michael Jackson’s family last week because they discovered he had a criminal record and felt he should no longer be near the family’s children, PopEater is reporting.Alvarez called 911 the day Jackson died. He worked at the family compound since last June, but the family felt there was something “off” about him, a source told PopEater.

Alvarez told LAPD that Dr. Conrad Murray stopped CPR on Michael to hide vials of Propofol. But he made that statement two months after Jackson’s death. Immediately after Michael died he did not tell this to investigators, straining his credibility.

Because he changed his story, and Joe Jackson was preparing a wrongful death suit against Murray, the Jackson family decided to check him out, a source told PopEater. They found a DUI and domestic violence complaint, according to the Web site.
